Kantar has now also released their June report focussing on the US market. Their data is derived from more than 240,000 interviews per year in the U.S. alone.
In the 3 months ending June 2013 Windows Phone slipped back from a high of 5.6% market share in April 2013 to only 4.0% in June.
Looking at the individual operators it seems Windows Phone has been pretty stable on AT&T, holding 4.5% market share, only slightly down from 4.7% in April 2013 when US carrier numbers were last released.
It is however on Verizon where we see the source of the problem.
There Windows Phone held 5.0% market share in June, admitted upped massively from 0.3% a year ago, but down significantly from 6.8% in April this year.
The issue is unfortunately amplified by the fact that Verizon sells nearly 40% more smartphones than AT&T, meaning a reduced market share there has a much greater impact on the US market than on AT&T.
Unfortunately AT&T has been Microsoft’s closest partner in the US, despite Verizon currently selling more Windows Phones, and we would suggest releasing top end handsets on all carriers may be a better approach that favouring AT&T with the best hardware the earliest.
